why does this game run so poorly after less than an hour of straight playtime? It starts just fine, on high or ultra settings. Then after about 2 missions things start slowing down and eventually I get a low memory warning, accompanied by a complete slowdown.F1_2004
Right now there are many, many issues with the game. One of them is a bug that causes overheating of the video card because the game isn't properly frame capped. In other words the FPS (frames per second) can reach sky high levels to the point of frying your whole videocard.I know the game has been patched yesterday but I don't think they've fixed this bug already.
Some cards and setups (SLI) are more vurnable than others. I have a GTX 260 and I've encountered this bug myself. I've seen the FPS litterally go over 450 on my own pc.
You can check if this is your problem (you're description tells me it could be) by measuring your FPS. Press CTRL-ALT+F while playing and your FPS will show up in the top left corner of your monitor. Funny enough, the FPS reaches the highest levels on simple loading screens.
I found a small workaround for this problem. If your FPS reaches insane levels go to the options screen and activate V-sync. This forces the game to the default screen refresh rate of your monitor (probably around 60) which means your video card doesn't have to work so hard. V-sync can cause an overall performance drop though so try the game on high first instead of ultra.
BTW
If you want to know the temp of your video card download a program called Everest which monitors the heat and fan speed in your pc and look at the temperature of your videocard. Idle it should be around 45/55 Celcius (depends on case, cooling, etc.) and at full throtle 65/70 is acceptable. If your CPU or GPU goes above 75 you're bound for trouble.
Also, visit the official US forums and check some threads in the technical support section. I believe there's even a sticky there about this issue.
